In order to understand how to operate the DFX-7, it’s best to start off with an
understanding of what it is we’re looking at exactly. The DFX-7 has a lot of great
features and tools that will prove to be a huge benefit for the variety of applications
you’re constantly facing on a continual basis. Let’s have a brief look at the screens
you’ll be looking at most often:
A. Repeatability/Stability Indicator – This indicator should be commonly used
in conjunction with the digital thickness values displayed. When all the vertical
bars are fully illuminated and the last digit on the digital thickness value is
stable, the DFX-7 is reliably measuring the same value 3 to 200 times per
second, depending on which measurement mode and features are enabled.
B. Battery Icon – Indicates the amount of battery life the DFX-7 has remaining.
C. Velocity – The material velocity value the DFX-7 is currently using or
calibrated for. Displayed in both English or Metric units, depending on the
what units the gauge is set for.
D. Feature Status Bar – Indicates the features currently enabled and in use in
the following order:
• Measurement Mode
• Differential Mode
• High Speed Scan Mode
• Alarm
Mode
• Gain Setting
E. Digital Material Thickness Value – Extra large font size for viewing ease.
